Re: Any plan for OTA support?

Carles Cufi

Hi David,

If I’m not mistaken the Mynewt bootloader includes support for serial “DFU” (more like app image management and transfer). Are you planning to port that as well as part of the mcuboot project? The reason I ask is that there have been some conversations regarding the future protocol that will be used to provide DFU over the different transports (serial, USB, BLE, 15.4, etc) and it would be good to know if you have taken any sort of decision in this regard.
If I’m not mistaken the serial code in the Mynewt bootloader uses parts of what’s called the Newt management protocol currently, so it’d be interesting to know if you plan to incorporate that into the project.
Also could you confirm that the mcuboot image will only be able to be overwritten using debug pins? (i.e. no DFU, OTA or otherwise of the bootloader itself).

We are working on the Mynewt bootloader (which is going to be its own project, called mcuboot). I have the OTA update as something that needs to be done, but I'm not aware of currently plans to implement anything.

Hi Linh,

I was actually asking myself the same question recently. I think Linaro has started working on making the Mynewt bootloader usable with Zephyr, but that is only the first step I assume.

Also, to add a bit to your question, are there plans for IP-based OTA only, or is “regular” BLE OTA support also planned? By regular I mean similar to the proprietary solutions that vendors offer today, where one can update the firmware using only GATT, without requiring IPSP or LE Connection-Oriented Channels.

Hi all,

Do you have any plans to support OTA framework on Zephyr?

Thank & Regards,
